Utility of the Bidirectional Glenn Shunt

The Annals of African Surgery, 2019
Background: Congenital heart disease (CHD) is a significant cause of childhood morbidity and mortality worldwide. Bi-directional Glenn Shunts (BDGS) form part of the surgical strategy used to treat CHD; no data exists on BDGS usage in the study locality.

Compression Suture Staple Repair of Simulated Gluteus Medius Partial Tendon Tears Provides Increased Contact Pressure Compared With Stepwise Bridged Repair

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To examine the contact mechanics of 2 different suture anchor configuration constructs for gluteus medius repair in partial‐thickness tears and to define an optimal distance for anchor placement in a biomechanical model. Methods Trochanteric bone was simulated using polyurethane foam blocks, and a polyurethane rubber was used as a surrogate for

Recent Non‐Suicidal Self‐Injury in Autistic Adolescents and Adults: Characteristics, Clinical Correlates and Suicidal Thoughts and Behaviors

Autism Research, EarlyView.
ABSTRACT Non‐suicidal self‐injury (NSSI) is prevalent among autistic adolescents and adults, yet research on its clinical characteristics, functions, and association with suicidal thoughts and behaviors (STBs) in this population remains limited. This study compared these domains between autistic adolescents and adults with and without recent NSSI.
